According to my Farnell Catalogue, Duracel Alkaline Manganese Cells are
rated as follows:

AAA     1175 mAH
AA      2700 mAH
C       7750 mAH
D       18000 AH
PP3     550 mAH

According to RS Datasheet 6294 (March 86) Alkaline cells rate as follows:
R(Load) = 40 Ohms (which draws only 39mA to start) Cell endpoint 0.9 volts.

AAA     700 mAH
AA      1000 mAH
C       4000 mAH
D       9000 mAH
PP3     400 mAH with R(Load) = 150 Ohms

Take your pick.
